PDB 6 August 2001: Bin Ladin Determined To Strike in US

Observation

The President received a 6 August 2001 brief stating Bin Ladin was determined to strike in the United States, including hijacking-related patterns.

Interpretation

Threat awareness existed at the highest level. Specificity is far below a date-time-place warning.

OBSERVATION: The 6 August 2001 President's Daily Brief, declassified in 2004, is titled 'Bin Ladin Determined To Strike in US' and discusses hijacking patterns and New York surveillance.

It does not name 11 September, the four flights, or the WTC as that morning's target. Officials have argued it was a historical recap. Critics argue it was actionable enough to raise defensive posture.

Supports H008-class intelligence-held-but-not-acted; does not by itself support a stand-down plot.
